Acer AL1715 17 in. Flat Panel LCD

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to answer and solve your problem. Your Compaq MV520 Monitor is always blinking every time you turn on your computer and you want to know how you can fix it? First, we need to troubleshoot the problem. I'm thinking you probably need to refresh the flicker rate on your monitor. The flicker rate is probably set on a low setting, which is causing you screen to blink (flicker). This can be bad for your health as well because it can cause eyestrain and headaches. Your monitor is a CRT (Cathode-Ray Tube) model. These types of monitors can cause a lot of screen flickering. Now that we've troubleshooted the problem, now it's time to solve the problem. There are two ways you can solve this problem. You can either refresh the flicker rate or you can buy an LCD monitor. LCD monitors flicker-free. My suggestion is that you refresh the screen flicker rate. To refresh the flicker rate, go into your System Preferences or Control Panel, click your operating system's appearance and display link and click your screen adjustment link. You may have to click your advanced settings link. Click your monitor tab and from there adjust you screen refresh rate. You may have to adjust your screen resolution before you refresh the screen rate. If you have to do this, make sure the screen resolution you choose supports you monitor's height and width as well as visibility. The higher the resolution, the higher the screen rate. The instructions I'm giving you may sound like this because I'm not sure what your operating system is. I'm not to familiar with Mac Operating Systems, but if you have a Windows Operating System and you need better detailed instructions, just reply back. I hope this decreases your screen flickering and gives you a better viewing experience.

Could be your refresh rate. Try the following:
* change your monitors refresh rate to higher availible.
* rt click on desktop then on properties and then display setting and then advance and then click on monitor tab and choose the highest availible and then click ok.

Would also attempt to move the screen forward and back to see if you have a pinched cable.

Also attempt to connect to an external monitor to see if it is your laptop monitor or the video card causing the problem.

Hope this helps.

It could be some loose connection, check both end of the VGA cables. If this does not resolves the issue, then check if you monitor is near a high voltage cable/magnetic waves/microvave(microwave oven).
If this still dosent resolves the issue, click on the OSD menu option on the monitor, see if you find Degasus, try and use that. If not you need to repair your monitor.

All the best.

Thanks for the git back: #1 I hooked up a second monitor (depressed fn+f5) and was able to view everything fine. No problem in any area. Ran Some security checks (malwarebytes,checked windows updates,Secunia PSI,and a virus scan. #2 I opened up the monitor and checked for possible loose connections. #3 brought up the graphics display and checked that 60 hrz was set and correct. #4 ran a backup of all my data from my other monitor,and I made the assumption that it was a bad monitor and I might save some money if I just bought a new laptop.Would like to here your comments. Sincerely : dandee4u3

If you bought it new in this last August, don't put up with it but get it fixed under the warranty. That is what warranties are for.

My screen flicker on xp but on win7 please help me?

The fault could be a faulty CCFL lamp or inverter.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

This is the same problem with my 4 VG800 Monitors, you should be able to find the correct capacitor on your monitors by following the same procedure, I'm sure the boards are similar. Just get the correct value capacitor and try it in parallel with the initial filter capacitors right after the DC power in.

Alright, I had 4 VG800 monitors with the exact same problem. The front led is blinky OR constant reddish/orangish OR picture is white with colored vertical lines OR no picture with whistling from the back of the monitor and backlights illuminated. All problems have the same solution. You need to disassemble the monitor (2 screws on the back, remove lower front button panel, remove 2 screws holding panel in and remove speakers, then remove panel and unplug speakers. Now remove lots of tape and screws from the cover in the center of the monitor). Now that you've exposed the amplifier board and the VGA to LVDS board, you want to look for the pair of 25V 100microfarad capacitors that are nearby the DC power in (they are right next to the black "100" inductor). Desolder the capacitor farthest from the DC jack and replace with an electrolytic with the same specifications. If you want to check that this is the correct solution please put the new capacitor (WATCH THE POLARITY) in parallel with the capacitor there want watch the front panel indicator go green and the monitor work properly.

I'll be posting and Instructable entry in the next few days on the process, watch for the username Waterppk on the website www.instructables.com
